To all whom it may concem:

Be it known that I, JOHN J. TEMPLE, a. `citizen of the United States,'residing at Kalamazoo, in the count-y of Kalamazoo and State ofMichigan, have invented a new and useful Improvement in Plaiting Devicesof` which the following is a specification.

My invention relates to certain new and useful improvements in plaitingdevices, and is :tully described and explained in the specificatio-n andshown in the acconpanying drawings, in which:

Figure l is an end view of my device, showing the same in its relationto a sewing- 'machine;Fig. 2 is a front elevat-ion of the device with 'apart of the frame broken away to show the interior Construction; Fig.

3 is a section'on the line 3-3 of Fig. 2, looking in the direction ofthe arrow; Fig. 4 is a section in the line 4: of Fig. 2, looking in thedirection of the arrow, but showing certain of the parts only; F ig. 5is a fragmental section on the line 5--5 of Fig. 2, looking in thedirectionof the arrow Fig. 6 is a longitudinal section on the line 6-6of Fig. 4, looking in the direction of the arrow, the View being fromthe rear as shown in Fig. 2; Fig. 7 is an elevation of the cam lookingdownward thereon, and Fig. 8 is an end View of some of the plaitingfo-rks showing the manner of their rotation and operation.

Referring to the drawings :-A is a frame made in the form of a ho-llowmetalbox which, in practice, is placed immediately in front of theoperative head of the sewingmachine although, as will presentlybe eX-plained, thesewing-machine might be dispensed with, other devices takingits place, although the -sewing-machine is the preferred method offiXing the plaits; Extending longitudinally of the frame is a stationarynon-rotating shaft B, upon which is inounted a rotatable sleeve C, to'one end of which is Secured an internal gear C meshing with a pinionaupon a shaft 6 which in turn bears a large gear (3 The gear 0 in turnmeshes with a pinion 0 on ,a shaft C which extends from the end oi" thebox-like frame A and carries a pulley 0 suitable for engagement with thebelt of the sewing machine. The direction of rotation of the variousparts is graphcally represented by arrows appear-ing on Figs 1 and 3.*The 'sleeve C has rigidly attached to it two plates 0 C which supportlongitudinally movable rods D, each of' whichis also cap'able of alimited oscillatory movement of 'rotation about its own aXis. Each ofthe rods D is surrounded by a spring d which tends to hold it towardthat end of the plaiter which is adjacentto the operativemechanism ofthe sewing-machine head,

in Fig. 2, and at the right in Fig. 6. It will be noted that the rods Dare even in number, andthat the alternate rods have that istoward theend which is at the left i their springs wound about them in oppositedirections, so that each spring will tend to impart to its rod amovement of rotation opposte in direction to that of the adjacent rodson the two sides. Stop-rods D (Fig.

6) ,eXtend between the two plates C 0 just w inside the rods D, as shownin F ig. t, and each of the rods D has a stop-pin' (l extendingtransversely through it (Figs. 4 and-6), the stop-pins in adjacent rodslying on opposit'e sides of the corresponding rods. As shownein Fig. 4,the relation of the rods being such that each spring will tend to rotateits rod in the proper direction until the 'stop-pin strikes thecorresponding stop-rod,

whereupon the rod will be held against further rotationby the pressure`of the spring.

The stationary shaft B carries an external segmental pinion E, and aninternal segmental pinion F is mounted in the france A in a' staggeredrelation with reference to the segmental pinion E. Each of the irods Dcarries a pinion 'D the pinions D upon the, adjacent rods beingstaggered with' reference to each other, so that when the rods are intheir most advanced position longitudinally, the pinions on one rod willstrike the segmental-pinion E, while the pinion on the next'rod willstrike the pinion F, and so ton. By this means, as the sleeve is rotatedthrough the gear-mechanism described, carrying with it the plates androds D, the rods will not rotate with reference to the plates .untilthey reach nearly their lowest point' in' their movement of revolutionabout the shaft B, whereupon they will be given the' short movements ofrotation about their own* aXis, each rod in an opposite direction to thelast and following. -It will be understood, of course, that the springs,stop-pins stop-rods are so arranged onthe 'corresponding rods D as to'permit this movement of rotation to take place against the action ofthe correspondingspring. Each of the rods D 'carries upon its endadjacent to the sewing-mechanism of the operative'head of the machine,(the left-hand end in Fig. 2, and the right-hand end in Fig. 6) two pinswhich form together a fork, the position of these pins being such thatwhen the rods are in their normal positions, a line connecting the pinswould be radial with respect to the shaft B.

A cam G is mounted within the frame A, the same being so arranged as toengage with the opposite ends of the rods D from the ends which carrythe forks (the righthancl end of the rods as viewed in Fig. 2, and theleft-hand end as viewed in Fig. 6). This cam is so arranged that as therods perforn their movement of revolution about the shaft they will,when they reach the furthermost point of their movenent in a forwarddirection, engage the cam and be moved forward against the influence oftheir springs as shown in Figs. 2 and 6. As the rods reach the lowestpoint in their course, they will reach an advanced dwell upon the cam(Fig. 6) and will remain in their forward position during the time whenthey are engaging the proper pinion and being rotated thereby.Immediately after this operation has taken place, the rods will run offthe cam G, and be immediately drawn back to position and simultaneouslybe given by the springs a movement of rotation to bring them into theiroriginal positions.

' The manner of operation of this mechanism upon cloth in the act ofsewing or otherwise making boX-plaits will readily be understood byreference to Figs. 1 and S. The naterial is fed in as shown in Fig. 1,at that point where the rods are just beginning to be advanced andbetween the pins thereon. The material follows a path concentric withthe movement of the rods lying between the forks thereon, until thebottom of the movement of the rods is reached, at which time each twoadjacent rods suddenly rotate in opposite directions and their forksthrow the boX-plaits in the manner illustrated in the drawings.Immediately after the formation of the plaits in this way, the rods arefreed from the action of the cam and are longitudinally retracted bymeans of the springs so as to free the material therefrom. Thisconcludes the operation of the plaiting-device as such. In practice, asa normal operation, the material thrown into plaits will be fed througha sewing-machine in the ordinary way and the plaits thus Secured inposition. It is obvious, however, that while sewing the plaits isprobably the most convenient manner of securing them in position, theessential part of this present invention is completed when the plaitsare formed and any other method of permanently securing them in theirfolds would be equally within the spirit of my invention, as forinstance, se-

curing the plaits by the application of an adhesive strip.

I realize that considerable variation is possible in the details ofConstruction of my improved device, without departing from the spirit ofmy invention, and I do not intend therefore, to limit myself to thespecific form herein shown and described.
